I'll take a stab at Regin's query, even though it was posted on the story site.
Simply put, a lot of drink.
We're talking military men here, and big men, even in comparison to your average Numenorean, I would think. So if it takes two 20 oz. ales to buzz me (190 lbs & an "aler" enough to stand a few), a third to slish me, and a fourth to slosh me. But I'm still with it, and that's the most I've ever had at a sitting. Double that to get a Temple Guard to the same point. Render him unconscious? Double it again. So that would be 16 x 20 oz. of ale, or 320 oz., which is how many gallons? I never was good at figuring that part out. So at any rate, a lot. Hope this helps.
